[gambit-list] Gambit in Emacs: REPL interaction

Hi I tried to use Emacs as suggested in the manual, and I also tried the Quack mode. Either I'm not using them right, or they just don't provide the functionality I need. I'm not looking for something as advanced as SLIME necessarily (which AFAIK only works with Scheme48), but at least something like what you get with ELISP: When you are editing a file, and eval an expression to the REPL, you get an answer in the minibuffer (which should temporarily expand if necessary) Also, if there is an error, you get a kind of pop-up window that's easy to dismiss and get to the top level of the REPL. I don't get these with Quack or Gambit mode. How do you make this work with Emacs? Commercial IDEs ruined this for me.
